Informed consent constitutes a fundamental ethical principle in medical practice. With the in-depth integration of generative artificial intelligence （AI） represented by Chat Generative Pre-trained Transformer （ChatGPT） with medicine， it has brought revolutionary development to traditional informed consent while also introducing new ethical challenges. ChatGPT offers features such as improving the readability of informed consent content， enhancing its comprehensiveness and accuracy， and increasing the convenience of obtaining informed consent. However， as the application of ChatGPT in informed consent is still in the exploratory stage， it is imperative to proactively and fully consider the accompanying ethical issues， such as information security， liability determination， transparency， and fairness. This paper conducted an ethical analysis on the challenges faced by generative AI， represented by ChatGPT， in the application of informed consent and proposed countermeasures， such as upholding free and fully informed consent， strengthening the balance of rights and obligations in informed consent， and establishing a transparent and fair supervision mechanism. The aim was to promote the ethically compliant， orderly， and controllable development of generative AI in the field of medical informed consent.

One female patient with cancer pain due to bone metastasis from breast cancer was initially treated with Xinhuang tablets,diclofenac sodium double-release enteric-soluble capsules,paracetamol dihydrocodeine tablets and paracetamol oxycodone tablets,before being switched to controlled-release oxycodone hydrochloride tablets.She regularly took oxycodone hydrochloride sustained-release tablets 20 mg,q12h,no abnormalities were observed,and the dosage was increased to 40 mg,q12h due to poor pain control.The patient was diagnosed with 5-hydroxytryptamine syndrome after 1 d of intermittent recurrent tremor,myotonia,scalp sweating,restlessness and elevated blood pressure.When oxycodone hydrochloride sustained release tablet was adjusted to 20 mg,q12h and gabapentin capsule was added to 0.1 g,tid,the frequency of tremor and myotonia attacks slightly decreased,and sweating and agitation symptoms were not relieved.After 14 days,oxycodone hydrochloride sustained release tablets were stopped and morphine sulfate sustained release tablets 60 mg,q12h were replaced.Three days later,the patient's symptoms disappeared.During 5-month follow-up,the patient's pain was well-contrdled,with no change in the dose of morphine sulfate sustained-release tablets,and no adverse drug reactions observed.Using the Naranjo's Assessment Scale,the association between the patient's serotonin syndrome and the suspected drug oxycodone hydrochloride sustained-release tablets was evaluated as"probable".Thiscase highlights the importance for clinicians to closely monitor adverse reactions induced by rapid opioid dose escalation to ensure medication safety in patients.

OBJECTIVES: Obtaining informed consent from research participants is an ethical and legal obligation for medical researchers in clinical studies. Electronic informed consent (eIC) is increasingly being adopted in clinical research worldwide. However, there is limited data on Chinese medical researchers' knowledge and attitudes toward eIC. This study aims to investigate their knowledge, attitudes, and influencing factors regarding eIC use in clinical research. METHODS: This cross-sectional study was conducted using stratified random sampling. From June to August 2022, medical researchers from 8 tertiary hospitals were surveyed via an online platform (Wenjuanxing). A self-developed eIC knowledge questionnaire and attitude scale were used to assess participants' understanding and perceptions of eIC. Univariate analysis was employed to explore factors influencing attitude scores and the correlation between knowledge and attitudes. A generalized linear model was used to analyze associations between demographic characteristics and attitude scores, including the frequency of difficulties in using smartphones or computers, preferred device for using eIC, and their interaction effects. Stratified analysis was further performed for significant interactions. RESULTS: A total of 399 valid questionnaires were collected. The mean accuracy rate on the eIC knowledge questionnaire was (94.88±15.50)%. Of the respondents, 74.9% had heard of eIC, and 84.5% preferred using mobile devices over computers to access eIC. The median attitude score was 3.41 (3.18, 3.76), indicating generally positive attitudes. Specifically, 81.7% found eIC more convenient than paper-based consent, 79.7% considered it more efficient, and 51.1% believed it could fully replace paper forms. However, 60.7% expressed concerns about data security and privacy, and 89.7% believed that relevant laws and regulations need improvement. Spearman correlation analysis showed a weak positive correlation between knowledge and attitude scores (r=0.171, P=0.001). Univariate analysis indicated that the frequency of difficulty using devices and preferred device for eIC were significantly associated with attitude scores (P<0.05). After adjusting for confounding factors, the generalized linear model demonstrated that participants who occasionally experienced had difficulty using devices had significantly lower attitude scores compared to those who never had difficulty (β=-0.040, 95% CI -0.071 to -0.009, P=0.012). Those who preferred using PCs had significantly lower attitude scores than those who preferred mobile devices (β=-0.066, 95% CI -0.108 to -0.023, P=0.002). Interaction analysis showed a significant interaction analysis showed a significant interaction between age and preferred device (P=0.011), particularly among participants aged ≥45-year (P<0.001). No other interactions were found to be significant (all P>0.05). CONCLUSIONS Medical researchers in China generally have a high level of knowledge and positive attitudes toward eIC, though concerns remain regarding data security and privacy. Future promotion of eIC in Chinese clinical research should be grounded in ethical considerations and address the specific needs of older users and mobile device users, while also enhancing researchers' competencies in using digital tools and eIC systems.

Objective:To explore the application effect of " visual nursing map" in coronary artery bypass grafting (CABG).Methods:A retrospective analysis was made on 76 patients who underwent CABG in Beijing Friendship Hospital, Capital Medical University from June 2021 to June 2023. 38 cases admitted from June 2021 to May 2022 were included in the control group, and 38 cases admitted from June 2022 to June 2023 were included in the observation group. The control group was given intraoperative routine nursing, and the observation group was given "visual nursing map" nursing measures on this basis. The preoperative preparation time and intraoperative pause time between the two groups were observed and compared. The measurement data were expressed as mean ± standard deviation ( ± s), and t-test was used for inter-group comparison. Counting data were expressed as cases and percentages, and Chi-square test was used for inter-group comparison. Results:In the control group, the preoperative preparation time was (93.2±8.5) min, and the longest procedure was the placement of electrosurgical equipment and instrument trolley, which were (6.4±0.8) min and (32.6±3.5) min, respectively. The intraoperative pause time was (7.3±0.7) min, and the longest time was the unskilled nursing cooperation of proximal and distal vascular anastomosis and the incomplete preparation of sterile surgical materials, which were (2.2±0.4) min and (1.4±0.3) min, respectively. In the observation group, the preoperative preparation time and intraoperative pause time were significantly reduced compared with the control group after the use of "visual nursing map" management on the basis of the control group, which were (79.4±5.4) and (93.2±8.5) min, (4.4±0.6) and (7.3±0.7) min, respectively, and the differences were statistically significant ( P<0.05). Conclusion:The application of "visual nursing graph" in CABG can effectively reduce the preoperative preparation time and intraoperative pause time, and should be further promoted.

Objective:To summarize Chinese materia medica with estrogen-activity based on data mining and analyze their characteristics.Methods:Literature was retrieved from CNKI, Wanfang Data, Chongqing VIP, CBM, PubMed and Web of Science from the establishment of the databases to June 30, 2024, and Chinese materia medica with estrogenic activity were screened. Excel 2021 and KH Coder 3.0 software were used to perform statistical and network co-occurrence analysis on the efficacy classification of Chinese materia medica, properties, tastes and meridians, screening methods for estrogen activity, and applications.Results:Totally 121 kinds of Chinese materia medica with estrogen-activity were included in total. The efficacy classifications were mostly tonic medicines, heat-clearing medicines and blood circulation promoting drugs. The properties were mainly warm and neutral, the tastes were mainly sweet and bitter, and the meridians were mainly the liver, kidney and spleen meridians. The network co-occurrence analysis of the efficacy classification, properties, tastes and tropism meridians showed that the clustering relationship of tonic medicine-neutral-sweet-liver-kidney was the most obvious. The screening methods mainly included MCF-7 cell proliferation and uterine weight gain experiments. Their applications mainly covered osteoporosis, perimenopausal syndrome, lipid metabolism disorder, and premature ovarian failure, etc.Conclusions:Chinese materia medica with estrogen-activity or their components act on estrogen target cells or organs to exert estrogen-like or antagonistic estrogenic effects. This kind of Chinese materia medica can regulate the body's qi, blood, yin and yang, the function of organs and the fullness of Tiangui, as well as the Chong meridian and Conception Vessel, thus improving human growth and development, reproduction and aging. In the future, it is suggested to explore their effective components, mechanisms, bidirectional effect and safety on the basis of guiding clinical medication with the theory of TCM, combining with modern medical research techniques and evidence-based medical research.

In order to promote rational drug use in perioperative period, a perioperative clinical medication pathway system was constructed in the Affiliated Hospital of Qingdao University using the project management method of work breakdown structure (WBS). To establish this system, the following 7 tasks should be completed: requirement investigation of the pathway, formulation of drug usage standards, formulation of clinical medicine pathways, clinical communication and training, effect evaluation and supervision, informazation of medication supervision, and therapeutic drug monitoring, which were implemented by pharmacists of different specialties, respectively. After 4 years of effort, 6 general clinical medicine pathways were completed for antibiotics, analgesics, drugs in venous thromboembolism prophylaxis, nutritional support agents, airway management drugs, and proton pump inhibitors, respectively. These pathways had positive effects in improving the rational use of antibiotics, optimizing the postoperative pain management, and strengthening the risk assessment of thrombosis for patients in the surgical department. The personalized pathway constructed for the Cardiac Surgery Department and the multidimensional pharmaceutical intervention in the Anesthesiology Department also had remarkable effects. In conclusion, the construction of perioperative medication pathway system through WBS was helpful to refine the division of work tasks, reflect the value of pharmacists, and improve the quality of perioperative pharmaceutical services.

Objective:To analyze the characteristics of Fournier gangrene (FG) induced by sodium-glucose cotransporter 2 inhibitors (SGLT2i), and provide reference for clinical safe drug use.Methods:CNKI, Wanfang Med Online, VIP, PubMed, Web of Science and other databases (up to January 2024) were retrieved and clinical data on patients with FG associated with the 5 kinds of SGLT2i currently used in clinical practice in China were collected and descriptively analyzed, including gender, age, comorbidities, concomitant medications, onset time and clinical manifestations of SGLT2i-related FG, laboratory and imaging examination results, treatment and outcomes, etc.Results:A total of 15 documents were included in the analysis, involving 15 patients, with 12 males and 3 females. The age of these patients ranged from 34 to 72 years, with 11 cases being over 50 years. Dapagliflozin was used in 7 cases, empagliflozin in 6 cases, canagliflozin in 2 cases, and no related reports on ertugliflozin and henagliflozin were collected. The main clinical manifestations of the 15 patients were redness, swelling, pain, abscess or purulent discharge in perineum, scrotum and perianal, etc. The time from application of SGLT2i to onset of FG ranged from 1 month to 6 years. Wound secretion bacterial culture was performed in 10 patients, and the results were all positive, including 9 cases of bacterial infection and 1 case of mixed infection of bacteria and fungi. All 13 patients who underwent imaging examinations had imaging manifestations related to FG. SGLT2i were discontinued in all patients. After treatments with broad-spectrum antibiotics and surgery, 14 cases were improved and 1 case was cured.Conclusions:SGLT2i has the risk of causing FG, which is more common in males. The clinical use of SGLT2i should be monitored closely. Secretion culture and imaging examination are helpful for the diagnosis of FG. The patient′s prognosis is good after discontinuation of medication, symptomatic treatment, and surgery.

Objective To investigate the protective effect of Liraglutide in rats with diabetic kidney disease(DKD)by regulating the nuclear factor E2-related factor 2(Nrf2)/glutathione peroxidase 4(GPX4)ferroptosis signaling pathway.Methods Twelve male Sprague-Dawley(SD)rats were randomly divided into normal control(NC)group,DKD group,and Liraglutide treatment(Lir)group,with 4 rats in each group.The 24 hUAlb,TC,TG,LDL-C,serum creatinine(Scr),BUN,ferrous ion(Fe2+),the activity of glutathione peroxidase(GSH-Px),and malondialdehyde(MDA)were detected in each group.Hematoxylin and eosin(HE),periodic acid-Schiff(PAS),and periodic acid-silver methenamine-Masson(PASM-Masson)staining were used to observe the pathological changes of the kidneys.Immunofluorescence was performed to detect the localization and expression of reactive oxygen species(ROS)in the renal tissue.The protein expressions of Nrf2 and GPX4 were detected by Western blot.Results Compared with the NC group,the levels of 24 hUAlb,Scr,BUN,TC,TG,LDL-C,MDA,ROS,and Fe2+were increased(P＜0.05 or P＜0.01),while the expressions of GSH-Px,Nrf2,and GPX4 proteins were decreased in the DKD group(P＜0.01).Compared with the DKD group,the levels of 24 hUAlb,BUN,TC,TG,LDL-C,MDA,ROS,and Fe2+were decreased(P＜0.05 or P＜0.01),and the expressions of GSH-Px,Nrf2,and GPX4 proteins were increased in the Lir group(P＜0.01).Conclusions Liraglutide may exert a protective effect in DKD by upregulating the Nrf2/GPX4 signaling pathway and inhibiting ferroptosis.
